I want to CANCEL my contract!

I want to cancel my contract as I signed up for the SPECIAL on the 2GB for R94 not R99 and now I have to be forced to pay R109 *shocked!* <br> I was even surprised and had to be forced to pay for the callerID which I thought just like prepaid it should come with the sim card already activated! To think I changed from MTN thinking I was getting a better deal for 2GB for only R94!!!!its upsetting and Yess I want to CANCEL!mxm!
